While the overall quality is a disappointment, some of your observations (presented as criticism?) bear a closer look. The finish on the hammer, trigger, safeties, etc. on original G.I. guns didn't match the slide and frame, as the small parts were finished separately; some guns had parkerized slide and frame, with blued small parts. G.I. mags are blued, not parkerized. The extensive use of cast parts is probably the biggest disappointment. An M1991A1, with the cast parts replaced by forged or barstock, would be closer to the mark, and cheaper, than the new '11A1.
